ELIE W. LABOMBARDE, or NASHU'A, NEW HAMPSHIRE.

WET PRESS.

Application filed February 16, 1920. Serial No. 358,981.

To all whom it may concern:

Be it known that I, ELIE W. LABoMBARon, a citizen of the United States, and resident of Nashua, in the county of Hillsborough and State of New Hampshire, have invented a new and useful Wet Press, of which the following is a specification.

The principal object of my invention is toprovide a machine which will efliciently remove water from pulp with the consequent improvement of the product and reduction of its volume, the latter reducing freight charges for transportation.

Another object is to exert a powerful and F positive pressure on the material.

Another object is to do away with thefelt carrier heretofore used with the result that I save the cost of the felt itself which is not only expensive but is not durable and I also save practically the entire expense of an attendant because heretofore each press has required an attendant to scrape off the material and to adjust the felt which tends to work out of alinement.

A feature of my invention is pressing mechanism which acts independently of the 1 conveying mechanism and in the preferred form the pressure is positive and the press ing mechanism is stationary with relation to the direction of the feed of the material.

Another feature consists in pressing mechanism which includes a reciprocating member.

The mechanism for delivering the material to the positive press and for removing it therefrom are also important features of my invention.

Other features will be pointed out below.

In the drawings Figure 1 is a plan of a machine embodying my invention;

Figure 2 is an elevation of the same;

Figure 3 is an elevation of the other side of said machine;

Figure 4t is a section on line 4-4; of Figure 1;

Figure 5 is a sectional view on line 5-5 of Figure 4;;

Figure 6 is a partial elevation showing the operating mechanism for themovable bed member;

Figure 7 is a section on line 7'7 of Figure'l Figure 8 is a sectional detail on line 88 of Figure 7 Figure 9 is a partial elevation of a modification of the pressing mechanism; and

Figure 10 is a detail of part of the bed operating mechanism of said modification.

Upon the bed or support A is suitably mounted the frame which comprises the receptacle part A, the supporting part A and the intermediate'part A these parts being rigidly connected to each other and supporting the various elements hereinafter described. I

The material, which maybe pulp with a considerable amount of water, is delivered to the receptacle at the mouth a and passes through opening a beneath walla which extends clear across the receptacle.

Within the receptacle is suitably mounted roll B whose surface is of wire cloth 7), the shaft Z) of said roll extending through one side wall of the receptacle and: having fixed to'it gear 6 meshing with gear 6 fixed on shaft 6 the latter being fixed to gear 6 meshing with gear 6 fixed to shaft 6 suitably connected to the source of power.

Roll D whose surface is of canvas d or felt or other suitable material is fixed to shaft 03 mounted on arm 01 pivoted to bracket (Z3 and on arm 6Z pivoted to bracket (F, the arms being connected by cross-bar d.

. Springs d and d tend to pull said arms downwardly and thereby hold roll D in proper relation to roll B so-that the latter, which picksup the material within the receptacle, will force the material against roll, D, rotating the latter which carries with it the material and I preferably remove more of the water by using roll E which is springpressed against roll D, said roll E being mounted on a shaft carried by arm 6 pivoted to arm 03 and by arm 6 pivoted to arm 0Z Spring 6 is connected to pin 6 on arm [Z and to arm 6 to; draw the latter toward roll D and I use a similar spring 6 for arm 6. I

The material carried around by roll D is scraped off by a scraping carrier F which extends across the roll D substantially throughout its length, said carrier compris- 'ing a scraping edge f carried by arms 7 which are rigidly connected to shaft 7 which is mounted to oscillate in bearing f atone side of the machine and in bracket f at the other side of the machine, said shaft being provided outside of said bracket with a gear i meshing with sector gear f whose shaft 7" is mounted on said bracket, said shaft 7" carrying also cam arm f which has a headed pin f engaged by the end f? of a coiled spring 7 also mounted on said bracket, said end f normally holding said cam arm in its lower position as shown in Figure 3 and consequently holding the edge 7 of the scraping carrier in engagement with roll D. Said carrier is moved away from said roll and carries the material onto the bed of the press by mechanism hereinafter described which acts on the peripheral surface of said cam arm.

When carrier F is substantially covered by the material which it has scraped from roll D it is swung over (by mechanism described below) and lays the material on fixed perforated bed G and on movable perforated members G and G bed G being slotted at g to receive arms 9. The fixed bed has fixed walls g 9 g and vertically reciprocating front wall G having slots 9* g and g to permit swinging movement of arms 9. When the material has been deposited on members G, G and G the last two-mentioned members are swung upwardly and inwardly to fold over the ends of the sheet of material onto the central portion, shaft 9 having fixed connection with member G and carrying gear 9 meshing with sector 9 which carries a pin 9 connected to spring 9 Sector 9 is operated by sector 9 and actuates gear 9 fixed on shaft 9 which is fixed to member G, sector 9 being mounted on shaft g which has a lug g" actuated by cam 51 on shaft W. The members G and G are swung back to normal position by spring 9" and then movable pressmember H moves down, said member H being mounted on rod h which extends across the machine and has near its ends rectangular blocks h h to ride in guides k and h the ends of rod'h being pivotally connected with connecting rods 7L and h and these being operated by cranks h" and it connected to opposite ends of shaft, 7L which near one end carries gear h meshing with gear h, the latter being carried by shaft h carrying pulley it" connected by belt h with pulley h on shaftrh which carries pulley it connected by'belt h" with pulley h on the power shaft. The connecting rod h carries a pin it which engages the cam surface of member f to swing the carrier F toward bed G and when the carrier has reached the end of its travel pin h enters notch f whereupon spring f acts to give an upward jerk to carrier F which efliciently separates the material from the carrier and then the spring 7 acts to return the carrier to its starting position, the cam surface of member f permitting this return gradually.

The member H gives a positive pressing action on the material to remove the water and when it is raised sufficiently the front wall G of the press moves down in guides Gr and G member G carrying pin G engaging in slot G of arm G which is pivoted to shaft G arm G being moved down by dog G fixed to shaft G said dog being actu. ated by cam G on shaft he. has moved down sulficiently the material is removed from bed G by the arms 9 and then spring G returns wall G to normal position.

The arms 9 are fixed to shaft G which carries gear G meshing with sector G oscillated in one direction by cam G" on shaft 7L acting on portion G and in the other direction by spring G.

The arms 9 lay the material on travelling apron K carried by pulleys l and K the shaft of the latter carrying pulley K conpected by cross belt K* to pulley K on shaft Apron K conveys the material to perforated metal roll L which carries it along between said roll L and another perforated metal roll L whichexert great pressure on the material and feed it between fixed plate L and plate L the latter being pivoted and normally held up in engagement with roll L by coiled springs L and L Passing out between plates L and L the material is carried off by belt L. The roll L is a floating roll actuated by roll L which is mounted on shaft L carrying gear L meshing with pinion L on shaft it while L is also a floating roll held in place by roll L whose shaft L is mounted in bearing blocks L and L mounted to move on guides L and L and adjusted for the desired pressure by coiled springs L and L.

In using my machine the material, which contains a relatively large amount of water, is fed into the receptacle and is carried up by roll B and between rolls B and D which squeeze out some of the water the axes of these rollsv being relatively ofiset to better pick up the material. The material is then carried around by roll D and more water is squeezed out between rolls D and E, the ma terial being carried around by roll D to the scraping carrier F, by which the material is scraped off until it substantially covers said carrier, which then swung so as to lay the cake or sheet of material on members G, G and G the carrier being given a slight spring jerk upward as described to more effectually remove the material, the carrier then returning to its original position to scrape off more material. The next step is the bending over of the ends of the sheet by members G and G so that all the material is within the walls of the fixed bed G, the

members G and G then returning to normal position. Thereupon the member H is brought down into engagement with the material and exerts a very powerful and positive pressure which removes the water and When wall G the main shaft.

nae-mas renders the material of the desired consist ency, the material being at this time stationary with relation to the direction of the feed. The member H is then moved up, wall G is moved down and the arms 9' lift the sheet from bed G and, swinging over, lay the sheet on apron K which conveys the material to the rolls L and L which, by reason of their mounting, give a pulling or sweeping action to the material which is conveyed between plates L and L to removing belt L. 3

ln Figures 9 and 10 it show a modification of the positive press and of the carryingmechanism thereto and therefrom. In this modification the rolls M and iii are similar to rolls l3 and I), roll M" however being fixed to shaft m which is jonrnaled in blocks m (one being shown), said block being adjustable by hand wheel m member M is fixed and leads to curved member M Sprockets M and M (and others not shown) actuate belt M which is provided with dogs or dams M which move the material along members M and M into position on movable press member M which is flush with the top of member lid when the material is moved onto it, member M being moved by arms M" and M pivoted M and pivotally connected to arms N and M which are operated cam M on l fhen the material has been moved onto M the latter is moved down into the position in Figure 10, so that the top of member M forms the bottom of a pressing chamber, two walls of which are provided by members M and M two; other walls (not shown) being also provided. Therenpon the ot ier press member M is moved down to give positive pressure to the material, member M being n'ioiinted in guides such as M and being actuated by connecting rod ltl pivotally connected to wheel M mounted on the main shalt. ld hen the pressing has been done the member M is raised and member hi is moved up until its top is flush with members lei. and M whereupon the belt M is actuated and the dogs M move the material along flat member M and on to travelling apron M which conveys the material to the desired location for removal. It will be understood that the movement of belt M ls intermittent and that two belts are provided, one at each side of the pressing cham- The scraping by collars n and n pinned to the cross bar As the arms g carry the material over onto apron K the arms N and N are swung toward roll L to pe mit the material to be placed on apron K but as the material is so placed the arms N and N swing baclr to their vertical position so as to ensure separation of said n'iaterial -from arms g when the latter are swung back to bed that is to say, arms t and N make sure that the material will remain on apron K, arms N and N being so located transversely of the, machine that they will not interfere with the returnmovement of rins 9.
